Application filed August 5, 1910. Serial No. 575,757.

To all whom it may concern:

Be it known that I, HAROLD F. PARISH, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings. city and :State of New York, have invented certain new and useful Improvements in Metallic Structures Such as Doors and the Like, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to metallic building structures such as doors, windows, frames, paneling, wainscoting and the like, and the object thereof is the provision of means for permanently securing the members of the shall possess great rigidity and strength.

In order to describe the invention briefly, I have shown the same as embodied in a door, but it is to be understood that the same is applicable to other structural work of the character above referred to.

Figure 1 of the accompanying drawings shows in elevation a sheet metal door; Fig. 2 is a sectional view of the upper left hand corner thereof, and Fig. 3 is a perspective view of a section thereof on the line 33 (Fig. 2).

Similar reference characters are employed to.designate corresponding parts in all the views.

In the structure shown, the frame menibers, to wit, the stiles 1 and 2, and the top, bottom and lock rails 3, 4 and 5, are connected by means of interlocking slots and flanges, the slots being formed on one set of members and the flanges on the other set. The slots are, in the particular embodiment of my invention illustrated, formed on the stiles, and the flanges are formed on-the rails. The panel members 6 and 7 are also provided with flanges which project intothe slots on the stile members, and also project into similar slots formed on the interior margin of the rail members. These interlocking flanges and slots are shown most clearly in Fig. 3, in which the stile 2 is shown as formed with two marginal slots, one of which. 8, receives the flanges 10 formed on the end members, and the other of which receives flanges- 11 formed on stay members 12. This arrangement of the slots and flanges forms no part of my invention. These flanges and slots interlock tightly and hold the structure together with sufficient rigidity to enable it to be assembled and handled without further locking means; but some further fastening i'ncans by which the members of the structure shall be permanently locked together are required to fit the structure for actual service, and in order to accomplish this I cut away or form apertures or openings 15 in the walls ofthe slots so that the flanges of the interlocked members are exposed at various points, as shown in Figs. 2 and 3. The exposed surfaces of the different members are then united by filling the openings with molten metal which fuses the exposed portions of the'ditlerent members virtually into an integral structure. This is accomplished by a suitable welding apparatus, preferably one operating on the electric arc principle. The metal which is thus fused into the openings 15 completely fills them, and projects sufliciently above the surface of the structure so that the inequalities can be all ground away, leaving a perfectly smooth and even surface which when furnished cannot be distinguished from the remainder of the structure owing to the perfect union between the fused metal connections and the frame members of the structure.

I claim:

1. A metallic structure of the character described, having frame members provided with, interlocking slots and flanges, the slotted member being cut away to form openings at points to expose the flanges on the interlocked member, and fused connections in said openings which are united to the flanged and slotted members and fill the.

openings.

2. In a metal door, a sheet metal part having aninteriorly grooved flange, said riorly I grooved flanges at the inner edges '7 into notches and having Welded connecthereof, said stiflening members having tions with the stile flanges at said notches.

flanges adapted to enter the grooves in the AROL'D F PARISH stile flanges, said stile flanges having notches iv r I in the edges thereof, the respective notches Witnesses? and grooves being in communication, said FRANKVJGRINDEN,
